Online Discussion

We are using Piazza for course discussion.

  • Please use Piazza properly. It's a place for students to exchange ideas. Don't post "easy" or "random" questions without much thinking.
  • To encourage students to actively participate in Piazza discussions and provide high-quality answers, we will select two students with the best Piazza performance. The top 2 students will get 2% extra credits in the overall scores.

Grade Book

Your grades will be returned through GradeScope (for regrades) and finally imported into Canvas.

Course Information

Course Description

This course provides an implementor's view of database management systems. It covers fundamental principles and implementation techniques, issues, and trade-offs related to database management systems. Topics covered include storage management, buffer management, record-oriented file systems, access methods, query processing, and query optimization. This course is a must for those students wishing to explore database management as an area of research and/or who plan on taking CS223 or CS224. A significant portion of database systems research as well as industrial database and information system development deals with adapting the basic database techniques covered in this course to new advances in hardware and software technologies or to the requirements of different applications and data types.

Prerequisites: CS 122A "Introduction to Data Management" and (ICS53 - "Principles in System Design" or CS143A - "Principles of Operating Systems"). Please don't attempt this class without the required background! Doing so has not proven to be a great idea for students historically. :-)

Using Github

You are required to use Github to manage your source code. Here are the instructions about how to use github to manage your projects and do submissions. For a team of 2 students, each member is expected to do the best effort to make equal contributions. We reserve the rights to deduct points for *both* students if we see unbalanced contributions.

Grading Breakdown

Final Exam: 50%
Programming Projects: 50%

This mixture of grading criteria for CS222P is intended to give equal "excelling opportunities" to both thinkers and do-ers. It's also intended to avoid overly weighting either team-based performance or individual performance. This is a hands-on project class, so expect to put a significant effort into your projects. The exam will be comprehensive with respect to the course material and will also ping you individually with respect to project knowledge, so be sure that you and your project partner make design decisions together. The final exam will be closed-book, but you may bring an 8.5"x11" two-sided cheat sheet to the exam if you like.

For all the graded projects and exam, if you disagree with the grading, you can discuss with us within two weeks after they are returned. After that, all the grades will be finalized. For final exam, the disputation deadline is subject to change upon University's grade submission timeline, please refer to Piazza for further announcements.

Programming Project

This class is intended to teach the principles involved in DBMS implementation, so it will include a significant programming component. The project will be aimed at giving you a sense of what goes on inside a DBMS, and what the issues and challenges are in building a system "now" that will be managing data of various user-defined shapes and sizes "later". You will try your hand at record-based file storage, indexing, and relational runtime system programming (a.k.a. query operators). The language for the project will be C++ - hopefully you either have C++ experience or you have Java experience and can learn C++ quickly. Our assistant(s) will run the project, and they can provide you with additional suggestions for material to help you "spin up" on C++ programming, debugging, and tools in case you need to do a bit of remedial work on the side in order to tackle the project successfully. The course has the same requirements for both graduate students and undergraduate students.

Notice about Projects

  • Making teams: Project grades will be team based. Each team can have at most two people. Please let us know about your group by adding your team members' names Group Signup Sheet followed by the group id (please do so even if you are alone in your group). A student can always leave his/her team during the quarter with a notice at least two weeks prior to the next project's deadline. Also, please note that it is not permitted to join a new team after splitting.
  • The projects are doable by individuals, which can be more challenging but rewarding.
  • Students are allowed to add attributes, methods, and classes, as long as the public signatures provided in the codebase are kept and implemented. We will be testing your code by calling the methods that are declared in the signatures.
  • Students also have the freedom to use other open-source libraries or packages (e.g., Gtest and Boost) to implement and test their code. Just please make sure that you: (1) get the okay from us before using any additional packages; (2) list such packages clearly in your project document; and (3) write your makefile correctly so that your project can still be built by calling the 'make' command.

Project Late Policy

  • The official due date for each assignment is listed here on the wiki, and it is expected that students will turn most work in on or before that date.
  • We will offer a 24-hour "grace period" for each assignment, and will therefore accept solution submissions that are turned in within 24 hours of the due date (i.e., less than one day late). No need to ask - this time is yours in the event that you need it for some unforeseen reason. If you use it, your score will be deducted by 10 points (out of 100). You are recommended NOT to use the grace period, as you will lose not only 10 points, but also valuable time from the next assignment's working period for every hour that you run late.
  • Late assignments after the grace period will NOT be accepted, so do always aim to be on time! (Please don't even ask, as this is what the 24-hour grace period is intended for. :-))

Cheating Policy

Cheating is an area where the instructor for this course has absolutely no patience or sympathy whatsoever. You are all here to learn, and cheating defeats that purpose and is unfair to your fellow students. Students will be expected to adhere to the UCI and ICS Academic Honesty policies (and should see and to read their details). We run a software package to search for cheating cases in projects. Any student found to be cheating or aiding others in cheating will be academically prosecuted to the maximum extent possible — so you may fail the course with no option for a second chance. This policy will be strictly adhered to; no exceptions will be possible regardless of the impact it may have on your studies, your work plans, your visa status, or anything else. Don’t cheat and you won’t have issues. Just say no to cheating!

C/C++ Resources

Final Exam

Time: Mar 17th Tuesday, 4:00 pm - 6:00 pm at RH 101
Closed books, Closed notes. You can bring an A4-sized "cheat sheet." The exam will cover all the materials taught in this quarter.
